  • 3M+ chatbots created makes it one of the most widely used custom chatbot builders, with a proven reliability track record.

Ideal for

  • SaaS companies who need a customer support chatbot that answers questions from their help docs.
  • Internal teams building knowledge base assistants for employee onboarding and HR FAQs.
  • Agencies building white-labeled chatbot products for multiple clients.

Not ideal for

  • Complex multi-turn task automation — Voiceflow or Botpress handle branching conversation logic better.
  • Enterprise deployments needing on-premise, SOC2, or strict data residency — check Chatbase's terms carefully.
  • Developers building fully custom conversational AI — LangChain or Dify offer more architectural flexibility.

FAQ

What is Chatbase?

Chatbase is a no-code platform for building AI chatbots powered by GPT. You connect your data sources — website URL, PDF files, Notion pages, YouTube videos, Google Drive — and Chatbase trains a chatbot on that content. The chatbot answers user questions using only your data, with source citations. Deploy it as a widget on your website or access via API.

Is Chatbase free?

Chatbase has a free plan with 1 chatbot, 400,000 characters of training data, and 20 message credits/month. Hobby (~$19/mo) gives 2 chatbots, 11M characters, 2,000 messages/mo. Standard (~$99/mo) gives 5 chatbots, 11M characters, 10,000 messages/mo. Unlimited (~$399/mo) has unlimited messages. Team and Enterprise pricing available.

What data sources does Chatbase support?

Chatbase can ingest: website URLs (crawls all linked pages), PDF files, DOC/TXT files, Notion pages, YouTube video transcripts, Google Drive documents, and plain text. The content is chunked, embedded, and stored in a vector database for semantic search. You can add and remove sources and re-sync on a schedule.

Can I white-label a Chatbase chatbot?

Yes. Paid plans allow removing Chatbase branding and customizing the chatbot's avatar, colors, and name. Enterprise plans support custom domains for the chat interface. The API lets you fully embed the chatbot in a custom UI without any Chatbase branding.
